Note 7: This parameter is guaranteed by design but not tested. The bus switch contributes no propagation delay other than the RC delay of the On resis-

tance of the switch and the load capacitance. The time constant for the switch and alone is of the order of 0.25 ns for 50 pF load. Since this time constant is

much smaller than the rise/fall times of typical driving signals, it adds very little propagation delay to the system. Propagation delay of the bus switch when

used in a system is determined by the driving circuit on the driving side of the switch and its interaction with the load on the driven side.
